HYDRAZINE-COORDINATED Cu CHALCOGENIDE COMPLEX AND METHOD OF PRODUCING THE SAME

Abstract

A hydrazine-coordinated Cu chalcogenide complex obtainable by reacting Cu or Cu 2 Se and a chalcogen in dimethylsulfoxide in the presence of hydrazine and free of an amine solvent, and adding a poor solvent to the resulting solution or subjecting the resulting solution to concentration and filtration; and a method of producing a hydrazine-coordinated Cu chalcogenide complex, including reacting Cu or Cu 2 Se and a chalcogen in dimethylsulfoxide in the presence of hydrazine and free of an amine solvent, and adding a poor solvent to the resulting solution or subjecting the resulting solution to concentration and filtration.

         2 . The hydrazine-coordinated Cu chalcogenide complex according to  claim 1 , wherein the poor solvent is an alcohol solvent. 
     
     
         3 . The hydrazine-coordinated Cu chalcogenide complex according to  claim 1 , wherein the chalcogen is sulfur or selenium. 
     
     
         4 . A method of producing a hydrazine-coordinated Cu chalcogenide complex, comprising:
 reacting Cu or Cu 2 Se and a chalcogen in dimethylsulfoxide in the presence of hydrazine and free of an amine solvent, and adding a poor solvent to the resulting solution or subjecting the resulting solution to concentration and filtration.   
     
     
         5 . The method according to  claim 4 , wherein the poor solvent is an alcohol solvent. 
     
     
         6 . The method according to  claim 4 , wherein the chalcogen is sulfur or selenium.
